The project itself is almost always also the reward.

e.g., "$50 tier, get a copy of the game"

Unless none of the reward tiers involve the project itself, and are all things like t-shirts and stickers...

I disagree. "5$ donation, get nothing" wouldn't require a refund.

The project purpose is to make a game. That's separate from the reward tier "get a copy of the game". So if the project fails, the backers who bought a copy of said game need to get a refund.
